The after looks fairly good.
The after looks fairly good.
This was my drive home. It's a lot closer.

I know it's probably not necessary to keep posting up the logs and screenshots but I may as well keep doing it until my MAF is dialed in and I get a good usable reference for the VE table just in case someone new (like me) to this is looking for reference to see what it looks like from one adjustment to another.
I did increase my MAF from 2500-6000 by .75% just to tilt it on the rich side of 1.0.
Just as a note, my PE calls for 12.64:1. After getting the 6300+ MAF table more in line with that, the car 'feels' like it pulls easier.

After a few iterations the VE and MAF have to converge as the new maps are applied (i.e. stay the same).
Yes, when it seems to pull better that is a sign that the AFR is getting close to what the engine likes.
Just to update, Im on tune edit (6) and Im now slowly chipping away making small adjustments to the 6500+ cells of my MAF table. I think it is interesting to see how far off my MAD table was after I got the car tuned.

The shape of the MAF(6) table looks correct (polynomial, consistenty increasing slope, no jerks/jolts).
BEN(6) is looking very good (dead on 1.00) during both 3rd and 4th gear pulls (engine is loaded differently in each gear).
Good job
Joecar - Thanks a million. Wouldnt have made it this far without your help.
It makes so much more sense when someone is able to confirm the changes. Plus having my pid file fixed didnt hurt either
Now that Im fairly squared away with the MAF and VE, I need to work on the occasional stalling I get when I come to a stop. Doesnt happen all the time, but it is definitely more frequent with the AC on. I'll look over the idle tutorial and give that a go.
can this be done w/o having factory narrowbands installed just using my lc-1
